Description

Technical Field

[0001] This utility model relates to the field of fabric roll storage technology, and in particular to a fabric roll storage module for a cutting machine. Background Technology

[0002] During the use of fabric, it needs to be evenly unrolled into the machine for further processing. The unrolling process requires a fabric unwinding device. Traditional fabric unwinding devices have a simple structure, simply placing the rolled fabric onto a drum and rotating the drum to rotate the fabric for unwinding. During unwinding, there is no fixation in the left, right, front, and back, and the unwinding amount is not precisely positioned, which can easily lead to the rolled fabric becoming loose. In the improved technical solutions, some modules place the fabric roll on two rotating shafts, pressing it firmly against the surfaces of the two rotating shafts by the weight of the fabric roll itself. Then, the tangent property of the two rotating shafts to the fabric roll is used to achieve centered placement and unwinding.

[0003] As the variety of patterns in finished fabric products increases, it is often necessary to obtain materials from multiple styles of fabric. Therefore, it is particularly important to know how to store multiple fabric rolls in a limited space, especially since these fabric rolls may come from different manufacturers, resulting in different specifications. Utility Model Content

[0004] The purpose of this invention is to provide a fabric roll storage module for a cutting machine to solve the problems existing in the prior art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A fabric roll storage module for a cutting machine includes a frame, which is a steel structure frame. Lifting mechanisms are provided on both the left and right sides of the frame's interior. Each lifting mechanism includes a first rotating shaft, a second rotating shaft, a first sprocket, a second sprocket, and a chain. The first rotating shaft is rotatably mounted on the bottom inner end of the frame, and the second rotating shaft is rotatably mounted on the top inner end of the frame. The first sprocket is sleeved on the first rotating shaft, and the second sprocket is sleeved on the second rotating shaft. The chain is used to drive the first sprocket and the second sprocket. Multiple mounting blocks are evenly arranged circumferentially on the right side of the chain located on the left side of the frame's interior, and multiple mounting blocks are evenly arranged circumferentially on the left side of the chain located on the right side of the frame's interior. Each mounting block has a protrusion at its bottom and a through groove at the center of its top.

[0007] By adopting the above technical solution, the frame is a rectangular frame structure during use. A lifting mechanism is installed on the left and right sides of the frame. The two lifting mechanisms are used to clamp the two ends of the roll through the cooperation of the mounting blocks on the upper part, and to wind the fabric on the roll, thereby realizing the storage of multiple rolls of fabric. The vertical movement of multiple rolls is realized by the rotation of the chain of the lifting mechanism. The denser the mounting blocks are set, the more rolls of fabric can be stored.

[0008] In a further embodiment, the mounting block is movably connected to the chain.

[0009] By adopting the above technical solution, multiple pins on the chain are set as extended structures with protruding ends. These pins with protruding ends are evenly distributed, and bearings are fitted on them. Then, the mounting plate is fixedly connected to the outer ring of the bearing, which realizes the movable connection between the mounting block and the chain. During the rotation of the chain, the mounting block will be driven to rotate. When it reaches the highest and lowest positions, in order to prevent the mounting block from flipping and causing the two ends of the spool to fall out of the groove of the mounting block, the connection structure between the mounting block and the chain is changed to a movable connection. Under the action of gravity, the end with the protrusion at the bottom of the mounting block always faces downward.

[0010] In a further embodiment, tensioning structures are provided at the middle positions of the left and right sides inside the frame, and the tensioning structures are used to adjust the tension of the chain.

[0011] By adopting the above technical solution, the chain is kept taut at all times, preventing it from detaching from the first and second sprockets.

[0012] In a further embodiment, the tensioning structure includes a fixed plate, a sliding plate, a bearing seat, a round rod, a roller bearing, and a third sprocket. The fixed plate is fixedly connected to the frame. The sliding plate is slidably mounted on the top of the fixed plate. The bearing seat is fixedly mounted on the top of the sliding plate. One end of the round rod passes through the bearing seat, and the other end of the round rod is fitted with a roller bearing. The third sprocket is fitted on the roller bearing. A support plate is fixedly mounted on the front side of the fixed plate. A threaded hole is provided at the center of the front side of the support plate. A bolt passes through the threaded hole from front to back. The rear end of the bolt is pressed against the front side of the sliding plate. The axes of the first rotating shaft, the second rotating shaft, and the round rod are parallel to each other, and the chain meshes with the rear end of the third sprocket.

[0013] By adopting the above technical solution, the position of the front end of the sliding plate is restricted by the screw during use. The chain meshes with the rear end of the third sprocket, so that the sliding plate is subjected to a forward thrust transmitted through the third sprocket, the round rod and the bearing seat, thereby restricting the position of the rear end of the sliding plate and completing the restriction of the sliding plate. When the chain is loose, the screw is turned so that the screw pushes the sliding plate backward, thus completing the tensioning of the chain.

[0014] In a further embodiment, the first rotating shaft of the lifting mechanism located on the right side inside the frame and the first rotating shaft of the lifting mechanism located on the left side inside the frame are connected to both ends of the connecting rod via a coupling. The right end of the first rotating shaft of the lifting mechanism located on the right side inside the frame passes through the frame and extends to the outside of the frame. The extended end of the first rotating shaft is connected to the output shaft of the drive motor.

[0015] By adopting the above technical solution, the output synchronization of the two lifting mechanisms inside the frame is achieved.

[0016] In a further embodiment, the interior of the groove is provided with semi-circular grooves on the left and right sides, the cross-section of which is larger than that of the groove.

[0017] By adopting the above technical solution, the groove on the protrusion of the lifting mechanism located on the right side inside the frame has a semi-circular groove on the right side of the groove, and the groove on the protrusion of the lifting mechanism located on the left side inside the frame has a semi-circular groove on the left side of the groove. The cross-sectional area of ​​the semi-circular groove is larger than the cross-sectional area of ​​the groove, so that it can be matched with the specially structured scroll to prevent the scroll from moving left and right. For example, an integrally formed circular plate is set on the left and right sides of the scroll. The diameter of the circular plate is larger than the diameter of the scroll body, and the diameter of the circular plate matches the diameter of the semi-circular groove. The groove matches the diameter of the scroll body, thus completing the limitation of the left and right ends of the scroll.

[0018] In summary, this utility model has the following beneficial effects:

[0019] 1. Two lifting mechanisms are installed on the left and right sides of the machine frame. The two lifting mechanisms are used to clamp the two ends of the roll with the cooperation of the mounting blocks on the upper part, so as to wind the fabric on the roll and realize the storage of multiple rolls of fabric. The vertical position of the multiple rolls can be moved by the rotation of the chain of the lifting mechanism. The denser the mounting blocks are set, the more rolls of fabric can be stored.

[0027] like Figures 1-2As shown, a fabric roll storage module for a cutting machine includes a frame 1, which is a steel structure frame. Lifting mechanisms 2 are provided on both the left and right sides of the frame 1. Each lifting mechanism 2 includes a first rotating shaft 21, a second rotating shaft 22, a first sprocket 23, a second sprocket 24, and a chain 25. The first rotating shaft 21 is rotatably mounted on the inner bottom end of the frame 1, and the second rotating shaft 22 is rotatably mounted on the inner top end of the frame 1. The first sprocket 23 is sleeved on the first rotating shaft 21, and the second sprocket 24 is sleeved on the second rotating shaft 22. The chain 25 is used to drive the first sprocket 23 and the second sprocket 24. The connection is as follows: Multiple mounting blocks 3 are evenly arranged circumferentially on the right side of the chain 25 located on the left side of the machine frame 1, and multiple mounting blocks 3 are evenly arranged circumferentially on the left side of the chain 25 located on the right side of the machine frame 1. Each mounting block 3 has a protrusion at its bottom and a through groove at the center of its top. The mounting blocks 3 are movably connected to the chain 25. Tensioning structures 4 are located at the center of both the left and right sides of the machine frame 1. These tensioning structures 4 are used to adjust the tension of the chain 25. The tensioning structure 4 includes a fixed plate 41, a sliding plate 42, a bearing seat 43, a round rod 44, a roller bearing 45, and a... The three sprockets 46, the fixed plate 41 and the frame 1 are fixedly connected. The sliding plate 42 is slidably mounted on the top of the fixed plate 41. The bearing seat 43 is fixedly mounted on the top of the sliding plate 42. One end of the round rod 44 passes through the bearing seat 43, and the other end of the round rod 44 is fitted with a roller bearing 45. The third sprocket 46 is fitted on the roller bearing. A support plate 5 is fixedly mounted on the front side of the fixed plate 41. A threaded hole is provided at the center of the front side of the support plate 5. A bolt 6 passes through the threaded hole from front to back. The rear end of the bolt 6 is pressed against the front side of the sliding plate 42. The first rotating shaft 21. The axes of the second rotating shaft 22 and the round rod 44 are parallel to each other, and the chain 25 meshes with the rear end of the third sprocket 46; the first rotating shaft 21 of the lifting mechanism 2 located on the right side inside the frame 1 and the first rotating shaft 21 of the lifting mechanism 2 located on the left side inside the frame 1 are connected to both ends of the connecting rod 7 through a coupling. The right end of the first rotating shaft 21 of the lifting mechanism 2 located on the right side inside the frame 1 passes through the frame 1 and extends to the outside of the frame 1. The extended end of the first rotating shaft 21 is connected to the output shaft of the drive motor 9; the inside of the groove is provided with semi-circular grooves with a cross-section larger than the groove on the left and right. The groove on the protrusion of the lifting mechanism located on the right side inside the frame is a semi-circular groove with a semi-circular groove inside the groove on the right side. Conversely, the groove on the protrusion of the lifting mechanism located on the left side inside the frame is a semi-circular groove with a semi-circular groove inside the groove on the left side. The cross-sectional area of ​​this semi-circular groove is larger than the cross-sectional area of ​​the groove. This is to prevent the spool from moving left and right when it is matched with a specially structured spool. For example, an integrally formed circular plate is set on both sides of the spool. The diameter of this circular plate is larger than the diameter of the spool body, and the diameter of this circular plate matches the diameter of the semi-circular groove. The groove matches the diameter of the spool body. In this way, the left and right ends of the spool are limited.

[0028] Specific implementation process: Limiters are installed in the middle position of the left and right sides of the machine frame, facing forward. The limiters are used to restrict the position of the chain in this area. Because the reel is picked up and put in this area, there are requirements for the relative position of the two chains in this position. The limiter includes a linear motor and an L-shaped plate. The linear motor is fixed on the machine frame and is used to drive the L-shaped plate to move back and forth. One side of the L-shaped plate is used to abut the rear side of the chain in this area, and the other side of the L-shaped plate is used to abut the side of the chain in this area near the inner wall of the frame. In order to further restrict the front and rear position in this area, a protrusion can be set at the front end of the L-shaped plate to form a U-shaped structure.

[0029] When using the device, a threaded hole with a depth of not less than 20 mm and a diameter of 6 mm (national standard) needs to be drilled at each end of the roll. This size should then be provided to all fabric roll manufacturers. Once the fabric rolls arrive, they can be stored on the device by screwing in cylinders of different sizes into both ends of the roll. The cylinder is divided into three sections along the axial direction: a semi-circular groove-fitting circular plate section, a middle section that fits into the groove to supplement the length of the roll, and a threaded section for connecting to the roll.
